Television
Talking about televisions history, it’s became commercially available in the nineteen forties and the basic technology has revolved around the picture tube. The picture tube is a large cathode ray tube with a series of electron guns in rear of the tube. The electron guns shoot electrons at the front of the tube, which is coated with a fluorescent material. The fluorescent material causes the electrons to diffuse, the fluorescent material glows and through a series of signal modulations, a visible image can be seen.
Nowadays, it’s really cool and comfortable if we can watch our favourite movie or live match through big screen television, especially if we watch with high definition television (HDTV). Every moment on the screen will become special with HDTV. So I try to browse in the internet to find what televisions suit with me, off course suitable with budget too.
